I have done this before and it never ceases to amaze me. Try this

While sitting lift your right leg off the ground and rotate your foot clockwise. Now with your right hand draw the number six (6) in the air.

Give a thumbs up if this put a smile on your face 

Tried, completed and high-fived myself after doing it.

Try this.

Find a comfy chair. Sit down and raise your left arm (as straight as possible).Try to slap your left cheek with your right hand. What was the result?

Yahoo! I could do it too:) Big smile for TGIF!!

LOL
